METHOD 0F APPLYING .A GOVERNOR TO HORSE-POWER.

Specification of Letters Patent No. 5,769, dated September 12, 1848.

vhad to the annexed drawings o-f the same, making part of this specification, in which- Figure l is a. side elevation; Fig. 2 is an end elevation, and Fig. 3 is a horizontal section through the line a' of Fig. '1.

rlhe same letters indicate the same partsl in-lall the gures.

My' invention and improvement consists in applying to a vertical wheel sufficiently large to admit of a horse traveling on the interior of its periphery to propel it, a regulator, which will maintain its velocity at a uniform rate, irrespective 0f the freeness or laziness 'of the horse, who is compelled whether he pulls much or litt-le, to yperform a uniform amount of work by being removed farther from the vertical center of the wheel when he pulls least, and coinciding with or behind it when he pulls most. In the accompanying drawings a is the framework which supports the wheel and its appendages, b is the Wheel made in the form of a large drum, the periphery of which projects on one side of the arms suiciently far to admit of the animals traveling thereon which are employed to propel the wheel, the power thus obtained may be employed in the propulsion of machinery, and may be transmitted either from the periphery of the wheel Z) or from a drum or cog Wheel placed upon the rear end of the main shaft. On the opposite or front end of the shaft the wheel c is secured, which communicates motion to the governor Z through the pinion e and also gives motion to the wheels m 'n L z' through the pinion 0. When the wheel b is being revolved too fast, the governor CZ acting in the usual way through the bent lever p moves the pinion m into gear with the wheel la, which acting through the intermediate wheels turns the wheel yj and its axis .the screw s, from the left to right, the screw acting upon the pivot nut Will draw back they lever u by which the horse pulls which will bring him to, or back of the center, and thus diminish his action upon the wheel. l/Vhen the great Wheel is moving too slow, the action of the governor is reversed, the pinion a being brought into gear with the wheel h by sliding the shaft f into the socket g which will turn the screw s from right to left, and movethe lever u forward, causing the horse to walk before the center to bring his gravity into cooperation with his muscular force eX- erted in draft. f l

WVhen the velocity of the great wheel is within certain limits which may l be arbitrarily fixed, the governor holds both the Wheels m and a yout of gear with the wheel h and consequently the screw is for the time being quiescentfand the position of the horseA unchanged.

To keep the horse in his proper place, a cord fastened to his bit is reeved through the pulleys mm1/,2, passing over his back and terminatingat the levervu to which it is fastened at the point of draft, so that whenever p the latterv point advances or recedes there is a corresponding movement of the cord fastened to the head of the horse.

Belts or chains and pulleys may be used to operate the regulating apparatus in lieu ofthe cog wheels if they be preferred, and the cog wheels themselves may be differently arranged also, kif it be deemed advisable.

l/Vhat I claim as my invention, and desire to secure by Letters Patent, is- The method herein described of regulat- 8 ing and rendering equable, the motion of tread-Wheel horse-power for driving ma. chinery, by simultaneously changing the yposition of the adjustable beam on which the horses moving them pull, and the halter to which their heads are fastened, all herein set forth, by which they are compelled, without Whip or driver, to perform a uniform amount of duty.

In testimony whereof I have hereunto 9,5 signed my name, this eleventh day of May,

A. D. 1848. p
